3And focal length, can clearly capture images at different distances and light environments.
Camera imaging principle: the optical imaging system of the camera is designed in accordance with the principle of geometric optics, using the linear propagation of light and the law of refraction and reflection of light, with the photon as the carrier, the light information of a moment of the subject is transmitted to the photosensitive material by the photographic lens in an energy way, and finally becomes a visible image. When a camera takes pictures, it must control the right amount of exposure, that is, the right amount of photons reaching the sensitive material.
The principle of the camera is the convex lens imaging principle. Pinhole imaging is made by lightThe linear propagation forms the real image. Plane mirror imaging is a virtual image formed by the reflection of light. Magnifying glass imaging belongs to convex lens imaging, which is a virtual image formed by light refraction. Camera imaging belongs to convex lens imaging, which is a real image formed by light refraction. Slide projector imaging belongs to convex lens imaging, which is a real image formed by light refraction.
The imaging principle of the camera is to use the sensitive element to convert the light signal into an electrical signal, and after processing, the inverted image is transformed into a upright image for easy observation, and the obtained image is saved in the storage.
Traditional camera imaging principle The lens focuses the scene image on the filmThe photosensitive agent on the film changes with the light, and the photosensitive agent changed after the light on the film is developed and fixed by the developer, forming an image opposite to the scene or complementary color.
- perfect printing: Two different plates are used to print the front and back of the same substrate at the same time. block copy: A graphic negative used for printing. - Single print sheet-fed printing: Printing on sheet paper or other sheet material as substrate.

If it is a chemical, the specific name will be listed. Quantity, type of inner & outer packages: Quantity, type of inner & outer packages. Gross weight: Total weight in kilograms. Net weight: the net weight of the goods after removing the packaging. Box type, quantity & Type of container (Number, size, type of container) : If it is container transportation, these details will be includedSection.
Silica gel means desiccant because one of them is made of silica gel, which absorbs the moisture in the bag very well, much more efficiently than ordinary desiccant such as calcium carbonate. As shown below, this desiccant needs to be placed in each bag to absorb water, ensure dry clothes, and prevent mold.
How to set up a scanning gun Connect a scanning gun to a computer. Install the scan gun driver. Configure scanning gun related software. measuringTest the scanning function. Connect the scanning gun to the computer: Use the attached cable to connect the scanning gun to the USB port or other corresponding interface of the computer. Make sure the connection is secure and not loose.
Consult the manual of the scanning gun and find the automatic carriage return setting diagram. The carriage return function is automatically added after the scan.
The method of setting the scanning length of the computer wired scanning gun is as follows: Before scanning, ensure that the scanning gun is connected to the USB port of the computer or the interface of the cash register system, and sound "beep" when connected. Install the driver. Connect the crystal end of the data cable to the baseThe other end is connected to the corresponding interface of the computer, and the computer will automatically install a driver and wait for the automatic installation. Make a match.
The method of setting the scanning length of the computer wired scanning gun is as follows: Before scanning, ensure that the scanning gun is connected to the USB port of the computer or the interface of the cash register system, and sound "beep" when connected. Open the software system of the computer, align the vision lv1300 with the single bar code of the commodity or electronic surface, and press the trigger key to realize the scanning of the bar code.
Install the driver. Connect the end of the data cable with the crystal head to the base, and the other end is corresponding to the computerInterface connection, the computer will automatically install a driver, waiting for automatic installation. Make a match. Scan the bar code on the base with a wireless scanner to complete the match. Note: Depending on the brand, the pairing method of the wireless scanning gun may be different, which can be consulted with the relevant product instructions. Open Excel.
The steps are: Connect the Comi scanner to the computer via USB cable, and wait for the computer to recognize the device.
